OT_J084555.1+033930: onset of rapid fading?

  Our observation last night (5 Feb) shows that 
the object faded by ~0.3mag in a day. 

YYYYMMDD(UT)    mag.  err.
20080104.63185 15.69V 0.01 Higashi-Hiroshima Observatory
20080105.66405 15.94V 0.03 Higashi-Hiroshima Observatory

The fading speed is larger than those during superoutbursts, 
and possibly indicating an onset of a rapid fading phase.
